Artificial ground motion synthesis method and device, electronic equipment and storage medium

The invention provides an artificial ground motion synthesis method and device, electronic equipment and a storage medium. According to the method, a frequency domain and time domain combined adjustment method is adopted, and spectrum-energy dual-matched artificial ground motion is synthesized by matching an acceleration response spectrum and an Arias energy accumulation curve. According to the method, a target ground motion is matched by adopting an iteration method, the power spectrum and the acceleration time history are corrected in sequence in each iteration so as to match the acceleration response spectrum and the Arias energy accumulation curve, iteration is stopped until the matching degree between the acceleration response spectrum and the Arias energy accumulation curve and the target ground motion is relatively high, and a spectrum-energy dual-matched artificial ground motion is obtained. The characteristics of an artificial ground motion are closer to those of an actually measured ground motion, a
